it's like this one:
Code:
DirectShowSource("D:\MU\movie.mp4")
sign01 = avisource("C:\mask01.avi")
sign02 = avisource("C:\mask02.avi")
trim(0,500)+trim(501,1000).overlay(sign01, mask=sign01.showalpha())+trim(1001,1500)+trim(1501,2000).overlay(sign02, mask=sign02.showalpha())+trim(2001,0)
Textsub("C:\Users\Cyclops\Desktop\subs.ass")
this frames aren't real, because the avs is really long, at least 26~30 overlays, but is the same script
